This invention relates vto.improveinents in water closets particularlyadapted, though not necessarily limited in its use, in boats, and one ofthe objects of the invention is to provide an improved water closet ofthis character from which the excrements may be read ily removed andwhich will operate efficiently either with or without the use of waterto flush the same. V

A further object is to provide an improved water closet of thischaracter which will operate efficiently either above or below the waterlevel without danger of flooding the closet.

A further object is to pro ide an improved water .closet of thischaracter which will be of simple and durable construction, effec: tiveand efficient in operation and which may be pernilanently or removablysecured in po Bit m- 7 To the attainment of these ends and theaccomplishment of other new and useful objects as will appear, theinvention consists in the features of novelty insubstantially theconstruction, combination andL arrangement of the several partshereinafter more fully de scribed and cl aimed and shown in the accompanying drawings illustrating this invention and in which 7 Figure 1 isa side elevation with the cover closed. I

Figure 2 is a front elevation, partly in section, showing the coveropen.

l igure is a vertical, sectional View taken on line 33, Figure 2. Figure4 is a vertical, sectional View taken on line 4;-4l, Figure 1.

Figure ,5 is an enlarged detail sectional view of a portion of thecylinder and plunger with the locking means for locking-the plungermembers together and for releasing them.

Refer-ring more particularly to the drawthe numeral designates generallythe bowl of a closet which is mounted upon a tubular support 11. Thesupport is provided with a b se flange 12 by means of which the c osetmay be secured in position. The c 12 is adapted to enter guideways 13 esecured .to a base orfloo'r 14 by means .uitable fastening devices 15.The guidevays serve as a means whereby the closet may be permanentlysecured inposition or adapts the same to be readily removed by slidingthe flange out of the guideWays 13.

Arranged within the tubular supporting base 11 of the closet is acylinder 16 which may be formed of any suitable material preferaply ofsome non-corrosive and durable material which may be separate from thebase 11 or may be constituted by a portion of the 7 support; Thiscylinder 16 is open at the top, and the bottom 17 thereof inclinesdownwardly from the periphery of the cylinder towards the diametriccenter to provide an opening 18 located preferably at the diametriccenter of the cylinder 16. Leading from the opening 18 is a dischargeoutlet 19 preferably in the form of a pipe which may be of asectionalconstruction, a portion thereof projecting through the wall of theupright 10 and to which pipe '19 may be connected a discharge pipe 20 ofany suitable character either flexible or non-flexible and through whichdischarge pipe 20 the excremenl-ts are delivered when the closet isoperatec.

A valve 21, preferably in the form'of a flap valve, is providedforclosing the opening 18 and this valve 21 is provided withacounterbalancing weight- 22. The weight 22 tends normally to hold thevalve 21 closed and the valve 21 operates from the underside of thebottom 1'7 so that in the event the closet is arranged below the waterlevel, any water en.- I

tering the pipe 19 from the outside will. assist in'holding the valve 21closed.

Under normal conditions the weight 22 is sufficiently heavy to hold thevalve 21 closed. 2 A catch basin 23 may be provided around the valve 21for any water which may pass through the bearingo-f theva'lve21 and thiscatch basin may be provided With a removable closure 24, which lattermay be removed when desired to permit the removal of water and foreignmatter from'the catch basin.

The cylinder 16 may be of any desired size and height and arranged toreciprocate therein is a plunger which consists of a body member 25 anda cover member 26, the two being pivotally connected as at 27; The bodymember 25 is preferably of an annular construction or is shaped to proide an opening 28 therethrough which is of considerable area and themember 26 is provided with a flange 29' adapted to engage and rest uponthe mem-' ber '25. If desired a suitable packing or gasket- 30 may beprovided in the member 25 to be engaged by the flange29 and thereby forma liquid tight joint. 7

Carried by the member 25 is a catch 31 which is pivotally connectedthereto by one end as at and a shoulder 33 is formed on the catch, theshoulder being adapted to engage over the flange 29 to lock the membersand 26 together.

lVithin the wall of the cylinder (shown in Figure 5 as being in thetubular support 11 and in Figure 3 as being in the wall ofthe cylinder1(3) is an opening 84 having an inclined bottom so that when the plungeris elevated. the upper end of the catch 31 will be directed into theopening 33, the catch. 31 being top heavy so as to cause the same tofall over its pivot as it reaches the opening l Vhen the'plunger 25 islowered the catch 31 will be moved by the upright wall of the cylinder(or the support 11) about its pivot to position the shoulder 33 over theflange 29 and thereby lock the members 25 and 26 together.

If desired suitable packing 36 may be pro vided in the member to form aliquid tight joint.

The member 26 may, if desired, be hollow.

The closet is provided with the usual seat 37 to which a cover 38 ispivotally connected as at 39. A link 40 is pivotally connected at oneend as at 41 to the inside of the cover 38and is pivotally connected atits other end 42 to the member 26 of the plunger and the member 26 isadapted to be moved with respect to the member 25 and about its pivot 27by means of the lowering movement of the cover 38.

When the cover 38 is raised the parts will be in the position shown inFigure 3, that is the catch 31 will be in a position to release themember 26 and the member 26 will be elevated by the link 10 and at thesame time the member 25 will be at the limit of its upward movmnent inthe cylinder. The valve 21 will also be closed either by the weight 22or by the 1' ressure of liquid under the valve forcing thevalve againstits seat. I

To operate the closet the cover 88 is lowered, the link 10 will thenswing the member 26 about its pivot 27 until the flange 29 engages andrests upon the member 25. This will occur before the cover is completelyclosed. A further closing movement of the cover 38 will cause theplunger constituted by the members 25 and 26 to be forced downwardly inthe cylinder 16. .As the plunger lowers the n'ieu'iber 25 travelingdownwardly in the cylinder will cause the catch 31 to swing about itspivot 32 to lock the members 25 and 26 together so that they will bothcontinue in a downward moven'ient and the member 26 will be held againstopening movement under force of any pressure exerted against the lowerside of the member 26 from within the cylinder 16. The lowering of theplunger will force the excrements from the cylinder 16 by swinging thevalve 18 about its pivot so that the excrements may be discharged intothe delivery pipe 19. As soon as the cylinder 1 6 is empty the valve 21will close and as the cover 38 is raised the plunger will also raiseuntil the end of the catch 31'reach'es the opening 34, at which time thecatch will enter the opening 34 to unlock the men'iber 26 with respectto the member 25, thereby permitting the cover 38 to be moved to a fullopen position and at the same time the member 26 will be raised to theposition shown in Figure 3.

Obviously the plunger consisting of the members 25 and 26 lockedtogether may be reciprocated in the cylinder 16 by aproper manipulationof the cover 38 and before the etch 31 enters the opening 34% to unlockthe member 26 from the member 25. v It will be manifest that it will.not be neces sary to install running water in the closet, but if desiredand on account of cleanliness water may be employed. i

lVhile the preferred form of the invention has been herein shown anddescribed, it is to be understood that various changes may be made inthe details of construction and'in the combination and arrangement ofthe several parts, within the scope of the claims, without departingfrom the spirit of this invention.
